As the host clearly stated, this place is only optimal for long term stay (30+ days) otherwise you'll end up planning your days with host's acquintance on site in mind since you'll either rely on him to get you in or wait for people to enter/leave the condo. Location is pretty mid tier too, about 15 minutes from MRT station, but you have to hop different lines to get to the main attractions of Bangkok.
If you're familiar with Bangkok and want to stay for extended period of time then snatch it without second thought. Definitely not recommended for first time visitors.
